Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic simulated candles fail to produce a realistic flame effect due to mechanical motion and light differences from real candlelight, leading to unsatisfactory user experience and potential mechanical issues.
Innovation Solution
A simulated flame tip with an LED lamp panel and light transmission cover, controlled by an IC module to create a gentle, flickering light effect, mimicking a real flame's sway and on/off changes, using a COB light source and symmetric light transmission surfaces for a realistic three-dimensional appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a mechanical swinging lamp cap is used to simulate flame flicker, then the flame-like swaying effect is improved, but the reliability deteriorates due to the swinging blade getting stuck or broken
Solution Approach 1:
The patent replaces the mechanical swinging lamp cap system with an LED lamp panel controlled by an LED control module. The control module sequentially turns on and off LED lamp beads in different array areas to simulate flame flicker and swaying effects without any moving parts, thereby eliminating mechanical failure while maintaining the visual effect.
Solution Approach 2:
The patent uses dynamic control of LED brightness and activation sequences to create the appearance of flame movement. The LED control module dynamically adjusts which LED beads are active and their intensity to simulate the random, organic motion of real flames, replacing static mechanical motion with dynamic electronic control.
2Shape
If a bulb with flame-shaped lamp cap is used, then the appearance simulation is improved, but the realism deteriorates because the light produced is totally different from real candlelight
Solution Approach 1:
The patent uses a light transmission cover with varying thickness where the center portion is thinner and the edge portions are thicker. This creates different light transmission characteristics in different areas, with the thinner center allowing more light through to simulate the bright core of a flame, while the thicker edges create a softer, more diffuse appearance at the flame periphery.
Solution Approach 2:
The patent employs COB LED lamp beads that can emit light in different color temperatures, and the light transmission cover material is selected to transmit and diffuse this light in a way that replicates the warm, yellowish hue of real candlelight, enhancing the realism of the illumination.
3Ease of operation
If LED lamp beads are turned on uniformly, then the simplicity of control is improved, but the realism deteriorates as it cannot produce flame-like on/off changes
Solution Approach 1:
The patent divides the LED lamp panel into multiple array areas with multiple LED lamp beads in each area. The LED control module independently controls different areas and individual beads, enabling complex flicker patterns and sequential lighting effects that mimic real flame behavior, while the control logic remains integrated and manageable.
Solution Approach 2:
The patent implements periodic on/off cycling of LED lamp beads with varying durations and sequences. Different areas are activated in alternating patterns, creating the characteristic flicker and pulsing behavior of real flames. The control module varies the timing and duration of LED activation to simulate the random, periodic nature of flame combustion.

Implementation Method 1
The LED lamp panel comprises a plurality of arrayed LED lamp beads packaged on a surface of a circuit board in a COB manner
Implementation Method 2
a light transmission cover refracts the light from inside to outside. As refractivity varies as the thickness of the light transmission surface changes, a light scattering range is large
Implementation Method 3
a light transmission cover refracts the light from inside to outside. As refractivity varies as the thickness of the light transmission surface changes, a light scattering range is large
